Volume loss converting DSF to Wav with Convolution

[simoncn]

What about applying a volume filter to increase the gain as part of the single-pass conversion? The gain would be chosen by the user as an average value. Not perfect, but probably better than applying no gain at all.

Another option (harder to implement) might be to first convert a short section of the audio file to come up with an approximate normalization value, then convert the whole file using this value. Does this make sense?

You also mentioned compression for 44.1 files. Is there an FFmpeg filter that can do this?
